Pattern analysis in a benthic bacteria-nutrient system

We study steady states in a reaction-diffusion system for a benthic bacteria-nutrient model in a marine sediment over 1D and 2D domains by using Landau reductions and numerical path following methods.We point out how the system reacts to changes of the strength of food supply and ingestion.We find that the system has a stable homogeneous steady sta

Different mechanisms of mitral regurgitation in hypertrophic cardiomyopathy: A clinical case and literature review

BackgroundAbnormalities of the mitral valve (MV) apparatus are typical features of hypertrophic cardiomyopathy (HCM).These abnormalities include leaflet elongation, thick leaflets, displacement of papillary muscle, and systolic anterior motion (SAM) of the MV anterior leaflet.Mitral valve chordal rupture associated with HCM is a rare but serious is
